A GPSTk example with some simple time classes and functions.

This is a port of the older C++ example1.cpp.

# In the GPSTk there are multiple classes to manage time, depending
# on the specific operation that we want to carry out. This modular
# approach eases handling the many different time systems used in the
# modern Global Navigation Satellite Systems.

# Note, however, that in the GPSTk the unifying class to do time
# Computations is the 'CommonTime' class.

# Read current time from system clock
systime = gpstk.SystemTime()

# Convert to 'CommonTime', the standard way to handle time at GPSTk
comtime = systime.toCommonTime()

# This is the typical way to handle civil time
civtime = gpstk.CivilTime(comtime)

# The YDSTime class is very useful for common GNSS tasks
ydstime = gpstk.YDSTime(comtime)

# This is a typical class to handle time in GPS system
gpstime = gpstk.GPSWeekSecond(comtime)

# Class to handle Modified Julian Date
mjd = gpstk.MJD(comtime)
